The Effects Of Heat Stress On The Human Body Temperature

Attempts are made to keep employees focused by frequent staff meetings, but people only partially pay attention as managers announce company developments. Management’s perceived need to continually push employees to act right is apparent in the way they handles the missing cover page on Peter’s TPS report. Stress To study stress in the work place, researchers often measure the existing stressors being dealt with by employees. The stressors may be either physical or psychological demands to which an individual responds and, if chronic or persistent, can lead to negative reactions or responses called strains. Physical task stressors include excessive heat, noise, and light, as well as job demands such as a time-pressured work pace, heavier workload, and the amount of hours worked.

5. Decreased muscle tone muscle tone and heat production cannot be reduced below basaal body requirements, therefore, this has a limited effect on decreasing heat production.

Body temperature is maintained within a fairly regular range by the hypothalamus that is found in the brain. The hypothalamus

The scientific, medical explanation about hyperthermia is that thermal regulation centers around the brain help to maintain the internal body temperature by adjusting the amount of salts in perspiration. Electrolytes help the cells in body tissues maintain water balance. In hot weather, a healthy body will lose enough water to cool the body while creating the lowest level of electrolyte imbalance. If the body loses too much salt and fluid, symptoms of dehydration will occur. The healthy human body keeps a steady temperature of 37 degree Celsius, in hot weather, the body perspires. As perspiration evaporates from the skin, the body is cooled, then the thermal regulating system in the brain helps the body adapt to high temperature.

Including human, most mammals and birds are homeotherm, whose body temperature maintains relatively constant,

Heat injuries are very serious and cause 240 deaths per year, they are the third leading

Lastly, thermoregulation/maintenance each and every individual needs to stay health. The body needs to keep the required body temperature. Although temperature can depend on the individual, it lies between 97 and 99 degrees Fahrenheit. The following helps in regulating the temperature, (Live strong, 2010) that Sweat glands are thermoreceptors when the body temperatures

When the body overheats, the increased temperature is detected by the hypothalamus and cooling methods are introduced. More blood is pumped to the skin surface thus ridding bodily heat. The sweat glands are stimulated to produce more sweat which is evaporated and cools the skin. The more heat lost during perspiration, the quicker the internal imbalance is rectified.

Stress can be caused by many different things within an organisation but the main causes of stress can be broken down into “six management standards” Anon (2009) how to tackle work related stress http://www.hse.gov.uk/ I used these areas to construct the chart below and discussed stress at a team meeting and asked my team to complete a Circle of influence around areas over which they felt they had no control Appendix 1 we also discussed what we / I could do to manage the six main causes of stress

In this lab the experiment was conducted to determine whether or not sweating has an effect on body temperature, or if sweating helps maintain a stable internal environment (homeostasis). The hypotheses was that if two cans that are filled with boiling water were wrapped in a wet and dry cloth then the can wrapped in the wet cloth will cool down faster. Every 30 seconds the temperature was recorded in degrees Celsius from the two cans wrapped in cloth, the cloth was held to the can using rubber bands. After 15 minutes of measuring the temperature it was concluded that the can wrapped in the wet cloth dropped in temperature much quicker. This is because as the water from the wet cloth evaporates it helps cool down the temperature of the boiling

Initially, the whole body model was validated by predicting the changes in Tc_N during cold water immersion and exercise conditions and was later applied for the firefighting scenarios. Cold water immersion and exercise at constant intensity are among the preferred scenarios for assessing the human body models [10]. Both the ambient temperature and the overall heat trans-fer coefficient (h) values can be varied or kept constant. This allows the model to demonstrate its capability to evaluate the influence of variations in the environmental conditions on the body temperatures. The whole body model incorporates variations in metabolic heat generation rates, local blood perfusion rates, shivering, and sweating to compute the variations in Tc_N,

Alcoa defines heat stress as the total heat load on the body arising externally from exposure to heat in the workplace, and internally from metabolic heat production associated with physical activity. Alcoa safety department works all summer and any time that heat will be major hazard to the employees. There are three disorders and diseases

I would like to conclude on a few points that we have discussed. The term stress was coined by Dr. Hans Selye from the University of Montreal and the basic definition of stress is the body’s response to any demand placed on it, pleasant or unpleasant (Cunningham, 2000). Some major causes of stress are “high physical, mental and or emotional demands, lack of variety, short work cycles, fragmented or meaningless work, underutilization and high uncertainty of work” (NOHSC, 2000, P. 29). There are also psychological stressors that affect workplace but that I will save that for another

Thermoregulation is the maintenance of a stable body temperature, even under external conditions. In humans, this temperature is about 37 degrees Celsius, although the normal range is from 35.5 to 40 degrees Celsius. Having a range allows for variation in the factors that can impact the body temperature. Some of these factors might include exercise, circadian rhythm, hormone levels, the temperature of the surrounding environment (ambient temperature), and food intake.
